The last 2 bytes are a reason code; the first 2 are a reason qualifier. Unfortunately I can't find 1004, but I may have been looking in an old manual. >... >Has anyone seen this?

GetAddrInfo Failed: RetVal = -1, RC = 1, Reason = 0x78AE1004 Are you by any chance still on z/OS 1.2 or 1.4? If so, you might be running into this. There's a LOT not said in the APAR; something else is needed to cause this error. (We never ran into it on either 1.2 or 1.4.) I suspect there are other non-bug reasons to get this. >... > BPX1SOC: RetVal = 0, RC = 0, Reason = 0x00000000 > BPX1IOC: RetVal = 0, RC = 0, Reason = 0x00000000 >GetAddrInfo Opened Socket 0x00000000 >GetAddrInfo Only IPv4 Interfaces Exist >GetAddrInfo Searching Local Tables for IPv4 Address > Unable to find any local host table >GetAddrInfo Closing IOCTL Socket 0x00000000 > BPX1CLO: RetVal = 0, RC = 0, Reason = 0x00000000 >GetAddrInfo Failed: RetVal = -1, RC = 1, Reason = 0x78AE1004 >GetAddrInfo Ended: 2007/03/27 12:45:53.195911 >... This says that the Resolver first looked for local host tables and didn't find any. It doesn't mention trying looking for a remote name server before it fails. That seems odd. There should have been a bunch of stuff prior to the lines you included that relate to your RESOLVER parms in TCPDATA. It would be helpful to see these. They will say whether you are trying to use name servers or not, what order you search, etc. Could you show those? Feel free to obscure dataset names, IP addrs, etc, but please include the lines containing that info. It should look something like res_init Resolver values: Global Tcp/Ip Dataset = None Default Tcp/Ip Dataset = None Local Tcp/Ip Dataset = SYS1.TCPPARMS(TCPDATA) Translation Table = SYS1.TCPIP.STANDARD.TCPXLBIN UserId/JobName = zzzzzzzz Caller API = TCP/IP Sockets Extended Caller Mode = EBCDIC (L) DataSetPrefix = SYS1.TCPIP (L) HostName = SYSA (L) TcpIpJobName = TCPIP (L) Search = abcde.COM (L) NameServer = aaa.bbb.ccc.ddd (L) NsPortAddr = 53 (L) ResolverTimeout = 10 (L) ResolveVia = UDP (L) ResolverUdpRetries = 2 (*) Options NDots = 1 (*) SockNoTestStor (*) AlwaysWto = NO (L) MessageCase = MIX (*) LookUp = DNS LOCAL res_init Succeeded Pat O'Keefe ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
